String sort challenge

#1

bool compare(string a,string b){
if(a==b){
return a.length()<b.length();
}
return a<b;

}
what wrong i am doing in compare function

#2

This means if “abc” == “abc”
return length which is always equal that’s why they are same

Instead do this


bool compare(string a, string b){
	if(a.size() <= b.size() && b.substr(0, a.size())==a){
       return a.size()>=b.size();
    }
    else if(b.size() <= a.size() && a.substr(0, b.size())==b){
        return a.size()>=b.size();
    }
    else{
        return a<b;
    }
}
